a substance or material capable of posing an unreasonable risk to health , safety, or property when transported in commerce.
is a group of hazardous materials that share dangerous characteristics. Their are 9 hazard classes
any substance designated under the clean water act and comprehensive environmental response compensation and Liability act.CERCLA
Extremely Hazardous Substnances (EHS)
chemicals determined by the EPA to be extremely hazardous to a community during an emergency spill or release as a result of their toxicities and physical chemical properties.
individuals who are likely to witness or discover a hazardous substance release and who have been trained to initiate an emergency response notification.
Hazardous Materials Technician
individuals who respond to releases or potential releases for the purposes of stopping the release.
Hazard Communication Regulation
requires hazardous materials manufactures and handlers to develop written MSDS.
radiation equivalent to man.
applies to all types of radiation
takes into account the energy absorbed(dose) and the biological effect on the body due to the different types of radiation.
involves particles travailing in a wave like motion.
produced from: ALPHA BETA GAMMA
made up of waves of energy. non ionizing radiation comes from ultraviolet and infrared energy waves.
partials that will travel 3 to 4 inches and will not penetrate the skin.
can be contaminated by
particles will penetrate the skin and may travel from 3 to 100 feet.
can by contaminated by
gamma radiation is a naturally occurring high energy electromagnetic wave.
high penetrating power and travels at the speed of light.
will penetrate the skin and will cause injure to the internal organs if not shielded.
single celled organisms capable of causing disease in plants, animals , and humans.
the study of chemical or physical agents which interact with biologic systems to produce a response in organisms.
ability of a chemical to produce adverse health effects as a result of a short exposure.
when a chemical produces damage after repeated exposures.. May have long latency intervals, develop slowly or require years of repeated exposure before they are manifested.
Lethal Dose (LD-50)
a calculated dose of a substance which is expected to cause the death of 50% of an entire defined experimental animal population.
Lethal concentration Low (LClo)
Lethal Concentration Fifty (LC50)
a calculated concentration of ta substance in air, exposure to which for a specified length of time is expected to cause the death the death of 50% of an entire defined experimental animal population.
Factors Influencing Toxicity
Route of Exposure
Synergism, Antagonism, Potentiation
Information Provided by Manifest
proper shipping name
hazard class and division
DOT or UN identification number
any special hazards
first aid requirements
emergency contact number manufacturer
CHEMTREC or CANUTEC
Basic Procedures of safequarding lives at a Hazmat Event.
Initial assessment and response at an incident
Removing citizens from the affected area
Minimizing health hazards for responders
the process by with people, animals, and equipment are subjected to or come in contact with a HAZMAT.. the magnitude of exposure depends on the duration and the concentration of the material.
Objectives of Hazmat
recognize the need for additional resources
gather information regarding the release
identify the HazMat if possible
take appropriate actions to isolate the hazard and deny entry
the incident command system is based on modular design, it allows transition from small to large scale incidents.
Safequarding Lives at ta HazMat incident
Removing citizens from the affected area
limit spread of contamination
establish safe travel routes for public enforce perimeter security.
remain up-hill and up-wind
wait for qualified assistance
remain outside the designated perimeter.
Protection level A
selected when the greatest level of skin, respiratory and eye protection is required.
Protection level B
used in situations when the highest level of respiratory protection is require, for example, using SCBA.
Protection level C
used when the type of airborne contaminant and its concentration level are known.
Protection level D
used to afford minimal protection against nuisance contaminants only.
used in atmosphere contains no known hazards.
Sources to obtain On-site information
highway-bill of lading
water- located in the wheelhouse or with the Captain
substance which due to its concentration, quantity or chemical/physical properties may cause or contribute to an increase mortality & illness
any substance or material in any form or quantity which poses an unreasonable risk to safety, health and property when transported in commerce.
any substance to which exposure results or may result in adverse effects on health or safety of employees or any chemical which is a physical hazard or a health hazard.
